I liked to have a simple detector that i could use to sweep rooms after i finished a job. I usually just keep it in my pocket and use it almost like an ambient detector.

No frills
Straightforward meter. Has the clicker for audible checking and a concentration graph display on the screen. You can also clip it on and use it as an ambient monitor. All around good for safety when you're dealing with combustible gasses.

Very convenient
I like this meter because it's small and can go in a tool bag or even your pocket. If you know how to trace a leak and the meter has even decent accuracy and sensitivity all these testers are kind of the same. I recommend this simply because of the brand reputation and the design is super convenient

Cool display
I like the concentration display on the screen. This makes leak detection a lot easier than listening to the ticker. I mean, the ticker is still there and can work for you if you like that, but I guess I'm more visual.

safety first
I can work in some pretty shady environments and i gotta make sure there isn't an accident waiting to happen. Some of the installs i come to repair are downright embarrassing.
